The farmOS documentation project is officially launched: http://docs.farmos.org
This is just a first step - documentation is always an ongoing process - and a vital part of any open source project. We will continue to add and refine the content alongside all new code development.
All content is stored and developed in a Git repository hosted on Github: https://github.com/farmOS/documentation
All pages are written in Markdown, and compiled into a static site with Mkdocs.
